Development of a new process methodology which satisfies given criteria is a big challenge faced by most of the forging industries. The domain of competition is quite large and hence every firm aims at producing near net shapes thereby eliminating the need for machining and other secondary operations. The present investigation deals with the flow simulation of aluminium forgings conforming to AA 6061 specification and henceforth studies the mechanical characteristics of the flow simulation results. The aluminiuim AA 6061 component considered is precision forged with a hydraulic press in a die having geometrical interlocking. During precision forging it was difficult to achieve the required net shape of the component because of unsymmetrical location of small ribs on cylindrical surface and variation in the cross sections from bottom to top (i.e. unsymmetrical about both X & Y axis). Thus to eradicate the problem encountered, the flow simulation of the precision forging process was carried out and the mechanical characteristics of the flow simulation results obtained were studied.
